+variables.c
+	- delete_var: new function, just removes a variable from a hash table
+	  and frees it, without doing anything else
+	- make_variable_value: if we are trying to assign to a nameref variable,
+	  return NULL if the value is null or the empty string or not a valid
+	  identifier

+variables.h
+	- delete_var: new extern declaration

+subst.h

+builtins/declare.def
+	- declare_internal: if we are creating and assigning to a nameref
+	  variable, make sure the value is a valid variable name (checks done
+	  by make_variable_value via bind_variable_value) and display an
+	  error message, deleting the variable we just created, if it is not.

+builtins/declare.def
+	- declare_internal: turning on nameref attribute for an existing
+	  variable turns off -i/-l/-u/-c attributes (essentially the ones
+	  that cause evaluation at assignment time) for ksh93 compat
+
+builtins/setattr.def
+	- show_name_attributes: if asked to display attributes and values for
+	  a nameref variable, don't follow the nameref chain to the end. More
+	  ksh93 compat

+trap.c
+	- _run_trap_internal: use {save,restore}_parser_state instead of
+	  {save,restore}_token_state, like in run_pending_traps(); don't
+	  need to save and restore last_command_exit_value as a result
+	- _run_trap_internal: call {save,restore}_pipeline like in
+	  run_pending_traps()
+	- run_pending_traps: since we no longer run traps in a signal handler
+	  context, do not block and unblock the trapped signal while the
+	  trap is executing
+	- run_pending_traps: allow recursive invocations (basically, running
+	  traps from a trap handler) with only a warning if the shell is
+	  compiled in debug mode.  If a caller doesn't want this to happen,
+	  it should test running_trap > 0. signal_in_progress (sig) only works
+	  for the signals the shell handles specially
+
+bashline.c
+	- bash_event_hook: make sure we clean up readline if interrupt_state
+	  is set, not only when SIGINT is not trapped.  check_signals_and_traps
+	  will call check_signals, which calls QUIT, which will longjmp back
+	  to top_level, running the interrupt trap along the way.  Fixes the
+	  problem of signal handlers being reset out from under readline, and
+	  not being set properly the next time readline is called, because
+	  signals_set_flag is still set to 1.  XXX - might need to do this
+	  for other signals too?

+subst.h
+	- SD_GLOB: new define for skip_to_delim; means we are scanning a
+	  glob pattern.
+
+subst.c
+	- skip_to_delim: if flags include SD_GLOB, assume we are scanning a
+	  glob pattern.  Currently only used to skip bracket expressions
+	  which may contain one of the delimiters

+subst.c
+	- parameter_brace_expand: when expanding $@ as part of substring
+	  expansion, pattern substitution, or case modification, don't turn
+	  on the QUOTED_NULL flag.  The code that constructs the word to be
+	  returned from expand_word_internal expects a different code path
+	  when $@ is being expanded.  Fixes bug reported by Theodoros
